While I don't like acknowledging it, the limited 3DS hardware may have very well been more a hindrance for Ridley in Smash than some of us like to admit. If it was for Ice Climbers, then it'd most likely be for him regardless of his role.
Then again, you had that one 3DS Dead or Alive game which was where the idea for Hazardly was unfortunately taken from to begin with, but for Smash, the 3DS version of Gaur Plains didn't even have the Metal Face stage boss, so Pyrosphere would probably have been out of the question for that version.
Regardless of how you spin it though, it wasn't until Samus Returns that we had a Ridley appearance that was well executed/defined for the 3DS... May have helped if we had that before Smash 3DS was a thing (where Proteus Ridley could then have been ported to Smash 3DS), not that it matters now in concern or regards to Smash Switch.
